Hello,
I have some troubles with displaying BMP monochrome picture on display. I use the ugfx library with the 128*64 display (ssd1306 controller) and STM32F103CBT6; FreeRTOS uses HEAP4 memory manager. uGFX starts working in a dedicated task (uGFX init) and LOGOis displayed. In process task I try to drawing image (BMP 24*24 pixels).
void displayPainter::vPrintScreen(uint32_t numScreen, screenPayload_t& data)
{
switch (numScreen)
{
case 0:
{
static gdispImage myImage;
gdispImageOpenFile(&myImage, "gasoline.bmp");
gdispImageDraw(&myImage, 0, 0, myImage.width, myImage.height, 0, 0);
gdispImageClose(&myImage);
}
break;
case 1:// Gazoline for station in km
break;
case 2:// Error menu enter
break;
case 3://Error entity
break;
case 4://Eraze error
break;
case 5://No eraze error
break;
default:
//Startup LOGO and TEST
break;
};
}
But code breaks into the HardFault Handler in gdispImageOpenFile() function (in allocating memory procedure for priv->palette value). This error occures with images, strings and LOGO are drawn correctly.
I tryed to insert Image drawing code to uGFX initialization task. Same error occured.
What's the matter? What am I doing wrong? Thanks in advance/
